Claims.

This invention relates to a slipper, and more particularly Vto alWashable slipperfhaving a crocheted upper provided lwithlacingfmeansanchored to the sides rof the sole ofsaid -shoe,rand whereinthe'top sole, heel wedge, inner'and bottomLsoles are laminated toproduce a unitary type of footwear. l n

In various types of footwear, particularly where the uppers are made oftextile or fabric material,

it will be noted thatl the soles of said type offootwearare of suchalquali-ty that in timethey deteriorate rather quickly. Also, such types.of footwear-become soiled very easily and cannot bewashed, with theresult that withina short time they Aare discarded. Furthermore, theuppers -of-:said types of footwear arevusually made of canvas or othernon-yieldable--materiaL While the lower `or foot resting portion ismade'up of a-number of separate parts which, .uponwashing willfallapart. A n

In accordance with my invention, .it is desired to providewashablefootwear having` a iiexible elastic upper adapted to provide acertainamount of elasticity wherebyY the footwear readilyoonforms to.the sibe and shape .of the ,foot of the wearer. l

It `is, accordingly, an object ofv this invention, to rprovide a vnovel'type of easily assembled footwear whose parts are formed into .aunitary no nseparable iiexible product.

`Another, object of the present 'inventionis vto provide a .washableslipperhavin'g its component foot supporting parts laminated into va'unitary mass in which the sole and heel portion thereofarejindistinguishable one from the other.

One other objectY of the present invention is to provide a slipperhaving a crocheted lastex upper anchored to the marginal edge of theintermediate sole which in turn is fused to an inner and outer sole soas to form a unitary, integral slipper.

A more speciiic object ofthe present invention is vto,provide a washableYunitary slipper Iin which the marginal edge of the inner sole isprovided with a series of hidden or sealed holes having a chain or lockstitch. extending therefrom onto the marginal edge of the vsole topermit -easy anchoring thereto of a crocheted upper by means of `anysuitable stitch, which'is adapted'to conform with the shape `and size ofthe foot of the wearer. n

Another object of the present invention is to provide a novel, economic`method of forming anchoring means in the sole ofaslipperl and oflaminating the component part-s Ythereof 'to form A a washable type ofslipper.

Further features and objects of the present (cms-9) invention willbecomeapparent fromthe follow-v ing description taken -in connection with theaccompanying drawings, inwhich:

Fig. l is-a side elevation of a preferred kembodiment of the presentinvention;

Fig. -2 isa plan partly broken vaway view of the bottom of the'intermediate sole showing thetype of Astitching utilized for thepurposes of ...anchoring a-flexible upper thereto 4as hereinafterdescribed; 1 if Fig- 3 is a perspective fragmental detailedview of theportion shown in Fig. 2; y

Y Fig; 4 is a vfragmental detailed sectional; view taken on line 4--4 ofFig. ,1; and, i

Fig. 5 is a longitudinal Asectional Viewv .of-the I foot supportingportion of the embodiment prior to lamination of theparts'thereof.`'Referring now moreparticularly to l,the `drawings in 'which similarreference ynumerals refer to `like parts throughout, .there isprovided-a slipper II), having a hand-'crocheted upper 'IllA of anysuitable style or design. The upper IIuis made preferably of anelasticlexibletype of fsynthetic Y n yarn.

footwear said upper -I -I is crocheted asia complete closed in Unitedstates. Patent 2,387,320 -lissued October 23 1945, inthe name of Foster,mixed Withnylon thread or'any other'suitable'textile In themanufactureof my newtype of unit preparatory toits yconnection to thelower laminated foot supporting portion I2. Said foot supporting portion-.I2 as shown in Fig. Y1 ofthe drawings .is made of `severalparts whichare` laminated togetherin `any suitable manner either by. thermosealingor by cementing the same `*with anysuitable type of. adhesive material,such .as rubber cement. l

4It vwill be noted that foot supporting,.portion I,2pror to lamination,Aas shown more specifically in Fig. 5, furthermore, contains 4an outsideortbottom sole I3, made of any suitableiie'xible material, ysuch asleather or ne0lite, an intermediate sole I4, a wedge heel I5 and an'inner sole I6, provided with a sock lining I 1 on its upper surface.Said intermediate sole I4, vwedge heel I5 and inner sole IBjarevpreferably `made `of a mixture of cork andrubber andlend themselves toeasy laminationor thermosea'ling so as to form a unitary foot supportingflexible portion "I2, as shownmore clearlyin Fig. l. Prior to thelamination of said'par'ts, intermediate sole member I4` is perforatedand provided with a plurality-of holes or openings I8 arranged 'inseries alongfthe marginal edge yI 8 o'f said sole member I4. -Said holes`are--everily spaced alongthe periphery of saidsole member 3 I4 but areset inwardly of said edge sufficiently far to permit covering andsealing of said holes when forming the completed foot resting portion I2and to be sealed from view when the sole is laminated. Furthermore, bymeans of said holes I8, an overedge chain stitch may be formed extendingcontinuously and horizontally from the marginal edge I9 of theintermediate sole I4 as clearly shown in Fig. 3. This type of chainstitch providesV an anchor to which there is attached by means of threador lace 2l the crocheted upper I I. The thread or yarn used to makechain stitch 20 may be of nylon or other suitable strong thread or fibermaterial which will resist wear and tear and continued washing.

In the process of making the slipper, the soles I3, I4, and I6 areinitially swabbedwithrubber members are then laminated togetherby theapplication of heat and. pressure, whereby all of the parts are -weldedso as to make an integral laminated foot supporting portion. After saidfoot supporting portion has been made the upper I I is then anchored tothe chain stitch 20 in any suitable manner, for example as by anauxiliary stitching 2| Aas shown in Figs. land 4.

From the foregoing description taken in conjunction' with theaccompanying drawings, it will be noted that by my invention a suitableflexible type of footwear can be made in three sizes; small, medium andlarge, particularly of the slipper type, thereby obviating the necessityof making slippers according to the exact footsize. Also, by making suchtypes of footwear in the three sizes indicated, considerable savings incutting according to different lasts is effected. By. the use of anupperl in footwear made according to the present invention, it will benoted that such upper has a certain amount of elasticity so as toconform with the shape-and size of the foot of the wearer. In otherwords, this type of footwear is adjustable to different foot sizes.

Furthermore, according to my invention, it will be noted that theanchoring means or chain stitch 20 protrudes from holes or openings I 8,and extends horizontally from the margin of the intermediate sole memberI4 andis intermediate the inner and outer soles. 'Ihere is no danger ofthe chain stitch forming any contact with either the foot'of the weareror with the surface upon which the wearer of the slipper walks. Inaddition, said type of stitch 20 forms a part of the laminated footsupporting portion, thereby eliminating any possibility of saidstitching being broken. The openings I8 in intermediate sole I4 are notonly hidden from view but are also filled due to the lamination of solemember I4 with sole members I3 and I5.

It will also be noted that a footwear made according to the presentinvention has long wearing qualities, does not readily deteriorate andcan be easily washed without any breakdown of the ingredients of thefoot resting portion. Nor will footwear made according to the presentlydisclosed invention crumble or fall apart when exposed to dampness orwashed.

While a preferred embodiment of the invention has been disclosed, itwill be noted that modifications as to arrangement of parts, use ofmaterials and the procedure of their vuse may be 4. made withoutdeparting from the spirit and scope of the invention as claimed.
